Great calculator, however
I’ve really like this calculator however lately there seems to be an issue with programming. I had a program for the sulfur to convert Celsius to Fahrenheit and vice versa but for some reason it doesn’t work anymore so 212 Fahrenheit should be 100 Celsius. it comes up with something like minus one point something to the power of 6000 I wonder what the issue is?

The Perfect Calculator
The 42s was, in my opinion, the most elegant calculator ever devised during the golden age of HP engineering. This simulator perfectly recreates this legendary calculator and it adds some additional great features. It has several enhancements seen in the RPL calculators without introducing the shortcomings of the more complex interface. Put another way, this calculator is what HP should have done with the 48 line. I believe that Plus42 now deserves the crown of the best calculator. It is the perfect continuation of the RPN days, and since it lives on your phone, it is always at hand. All that for just under $10!
